They used Dementia Joe because someone that old, feeble, and demented is the perfect puppet and easy to control. Biden had no idea where he was or what he was doing, just what he was being told to do. The cabal used him to ram through all the unpopular and unconstitutional shit. Its why he rammed through a billion EOs in only a few weeks.

They are about to throw him under the bus and trot out Heels Up to save face for the Democrats. I predict the media and Democrat voters will conveniently and quickly forget about everything Biden did and celebrate "MUH FIRST WOMAN PRESIDENT! SO HISTORIC!" and now that they've rammed through everything that hurt everyday Americans and benefited the wealthy elites, she'll just stay mostly focused on "social issues".
